Material.—Four pygidia (repository numbers: NIGP−152080– 152082).

Remarks.—These poorly preserved pygidia exhibit morphology similar to that of Neseuretinus (see Turvey 2005: pl. 2: 8) in sharing a sharply turning anterior margin and relatively distinct terminal piece. The rimmed nature of marginal border in some specimens ( Fig. 11T, U) is unusual for reedocalymenines; Reedocalymene has the border that is rather flat than rimmed (see Peng et al. 2000: pl. 1: 1). No Neseuretinus −like cranidium with a pre−cranidial spine was found in the entire collection. It cannot be ruled out that the pygidium may be a dorso−ventrally compressed specimen of Vietnamia species (compare Figs. 8I 2, 9D 1, and 11S 1). The assignment to Neseuretinus is uncertain.
